问题 I'm creating a R shinydashboard with a big database that takes a while to load. Is it possible to create a progress bar that displays the information of the amount of data that has been read? (e.g., "Read X% of Z rows")? 回答1: R cannot tell you how many rows are in your data until the initial load is complete (I think). However, you can use the built in Shiny progress bar to give your users a message that the data is loading: x<-list.files() data<-data.frame() withProgress(message = 'Reading

问题 I have deployed an app in shinyapps.io and its working fine. I am running the app for only 5 minutes, but when I checked the metrics it shows a running time for about 0.7 hours. I found that there is a default idle time of 15 minutes, which I have changed to 5 minutes (minimum). I also noticed that, even after closing the browser window of the shiny app, it still shows the app as running in my dashboard. I assume that the app doesn't stop running when a browser window is closed and it will
